z  Level the bucket and other work equipment to the 

ground. 

z  Stop the machine on the level ground where there is 

no danger of stone falling, coasting or flooding. If it 

is necessary to stop the machine on a slope, wedge 

the wheels to prevent movement. 

3.4.2 Steps to Stop Engine 

z  Let the engine run freely for 5 minutes to cool all the parts equally. 

z  Pull the flameout control soft knob (if assembled). 

z  Turn the key to OFF position. And draw it out and keep in a safe place.

WARNING

 

Never pull the flameout control soft knob to stop the engine 

before the engine is cooled. 

 

3.4.3 Leaving Machine 

z  Use the ladder and handle to climb down facing the machine. Never jump down. 

z  Check whether there are particle-likes materials on the engine. If so, clean them immediately to 

prevent fire. 

z  Clean all the flammable materials around the machine to prevent fire. 

z  Lock the door and window, and draw the key. 

3.4.4 Do the Followings after Work Everyday 

z  Check the fuel reserves. 

z  Check the oil level of the engine oil pan and its cleanness. If the oil level is too high or diluted, 

find the reasons and solve them. 

z  Check the oil pipes, water pipe, gas pipe and other parts for leaking conditions. 

z  Check the gearbox, torque converter, steering unit, fixing of front and rear frame, and sealing 

conditions. And check whether there are overheating conditions. 

z  Check whether the rim bolts, transmission axis bolts and other pins are loose. 

z  Check whether the work equipment is in good working order. 

z  Check whether the wheel pressure and outside surface are normal. 

z  Add liquid oil to the adding points of work equipment.

z  Check the quantity of the brake oil by opening the oil bowl cover of the brake booster pump. 

z  Drain the water in the air tank from the water outlet valve. 

z  Clean the outside surface of machine and the inside of the bucket. 

3.5 Operations 

3.5.1 Prepare to Work 

Clean the working area, and fill-up any hollow spaces. Clear away the sharp stones and roadblocks 

that may break the wheels and operation. 

3.5.2 Modes of Work 

(1)  Loading Operation 

z  Work together with a truck which can help improve working efficiency especially for long 

distance transportation. 

z  When working together, the loader digs the material and 

the truck transports and unloads the material: 

There are generally two loading and unloading ways: 

z  Cross Load: 

The loader faces the material, then it moves backward 

after digging a full load and lets the auto-unload truck 

move into the position between material and the loader. This method costs the minimum time and 

can reduce the cycle time most effectively. 

z  “V” Shape Load: 

The auto-unload truck is fixed and forms almost a 

60°angle with the backward direction of the loader. 

After digging, the loader moves backward and turns 

the designated degree and moves forward to the truck. 

The smaller the loader work angle is, the more efficient 

the work is.   

(2)  Digging Operation 

„  Digging Piled Soil or Blasted Rock 

When digging piled soil or blasted rock, the loader should face 

the material and do as follows: 

z  If the bucket must be lowered while driving the machine 

forward, stop the machine when the bucket is about 30cm 

above from the ground, and then lower it slowly.

If the bucket hits the ground, the front tires will leave the     

ground and the tires will slip. 

z  The operator must slow the speed immediately when the 

machine reaches the material pile. Simultaneously step on 

the accelerator pedal, and enter the material pile with the 

bucket. 

z  Keep the bucket horizontal when loading the stockpile, but 

keep the dumping angle down when loading the blasted rock. 

Notice: 

Do not let the blasted rock go under the bucket which will make 

the front tires leave from the ground and slip. Try to hold the 

load in the center of the bucket; otherwise, if the load is on one 

side of the bucket, it will be unbalanced. 

z  Raise the lift arm to prevent the bucket from inserting too 

deeply while thrusting the bucket into the material. The tires 

will bring ample traction by raising the lift arm. 

z  If enough material is loaded into the bucket, operate the 

working equipment control lever to take back the bucket in 

order to load it fully.   

Remark: 

If the shovel edge moves up and down when thrusting material into 

the bucket or when digging, the front tires will leave the ground 

and slip. 

z  If there is too much material loaded into the bucket, the bucket 

must be dumped and titled quickly to remove the excessive load so as to prevent the material from 

dispersing during transportation. 

 

„  Digging and Shoveling Material on Flat Ground 

Lightly set the bucket edge leaning on the ground (see picture) 

when digging and shoveling material on flat ground. Be 

careful not to fasten the load to one side which will cause 

unbalance. This operation should be carried out carefully in 

gear .

z  Lightly set the bucket edge facing down. 

z  When driving the machine forward, operate the working 

equipment control lever to let the lift arm lower down to the 

proper position so that it can pick up a thin layer of the surface 

each time when excavating the soil. 

 

z  When driving the machine forward, shift the working equipment control lever backward and 

forward slightly to reduce the resistance.

NOTICE

 

Keep the two sides of the bucket cutting into the material equally 

to prevent only a single side working. Face the loader forward and 

never let an angle exist between the front and rear frame. 

 

(3)  Conveying Operation   
The loader must be used without a truck under the following conditions: 
z  The ground is too soft and not level, and the truck can not be used. 
z  When the transportation distance is within 500 meters, it is not economical to use a truck. 
z  The transportation driving speed is determined by the road condition. 
z  In order to get good visibility and stability, the bucket should be turned to its upper limit 

location(bucket lift-arm touch the upper limited block) and keep the lower pin connection point 
of lift-arm at the transportation position (400~500mm above the ground). 

 
(4)  Dumping Operation 
z  When dumping material on to trucks or into freight 

yards, raise the lift-arm to the position (forward tilt to 
the maximum position) where the bucket does not touch 
the carriage or material pole. And operate working 
equipment control lever to tilt the bucket forward to 
dump. Part or all of the material can be dumped by the lever control. Act slowly and gently 
during dumping to prevent the bucket from striking the ground. 

z  If the material sticks onto the bucket, move the working equipment control lever cyclically to 

allow the bucket to tilt forward or backward to shake down the material.
